Thomas Sydenham was an English physician. He was the author of Observationes Medicae (1676) which became a standard textbook of medicine for two centuries so that he became known as 'The English Hippocrates'. Among his many achievements was the discovery of a disease, Sydenham's chorea, also known as St Vitus' Dance. To him is attributed the prescient dictum, "A man is as old as his arteries."
